Those "Mens" boots are all essentially Chelsea boots, so, the main go-to for the bridge from men to femme, as far as the second half of the 20th century goes. I actually don't mind them, I'm not much into prints, but they are not that dissimilar from the blocky square toe boots a lot of women wore in the 70's and 90's. Just watch some off the older Friends episodes and you'll see them. Easy to pull off, and can be worn any way, really.
The stiletto boots from YSL are just another attempt at rebranding an existing boot, but with the gender-bender thing going on as well. I would love for there to be a demand for boots by men at that level, it just isn't there yet, and as I'm sure we are well aware, the more people continue to push this issue in attempts at social engineering, the more people push back. I sometimes wish people would quit 'fighting' for it, and just let people be. Courage is not extraordinary, it must be commonplace.
